I'm not asking you to replace the existing method of syncing this data in the cloud via a Windows Live account; this option just needs to be complemented with an offline option for syncing this data with Outlook.

This type of data is personal: Outlook contact files in particular can contain a full spectrum of personal information, from phone numbers and addresses to birthdays, anniversaries and names of family members. I'm not comfortable with sending this information to the Internet, regardless of how convenient it is and no matter how safe and secure it's supposed to be. It's not even my own information I'm trying to protect: it's the information of my family and friends, who didn't volunteer to have all these details about themselves sent online just because I got a Windows Phone.

If Windows Phone is going to compete with iPhone, it can't afford to go without basic features like this. As an iPhone user, I can tell you firsthand that I depend daily on the offline synchronization of my Outlook contacts and calendars; because, unlike Windows Phone, iPhone supports the offline synchronization of this data, along with the cloud-based alternative. Frankly, it's embarrassing to see less compatibility between 2 Microsoft products (Outlook & Windows Phone) than there is between Microsoft and Apple, its direct competitor!

Perhaps I've been somewhat harsh: they say you can only hate what you love. I'm a PC. I've grown up with Windows and I don't have any plans to ever own a Mac. I'm looking forward to owning a Windows-8 tablet. Yes, I have an iPhone, but it's a hand-me-down that I inherited by default. I want to end up with a Windows Phone. But,I'm not going to get one. I'm going to stick with iphone until Windows Phone wakes up and offers direct, offline synchronization with Outlook.

There are a lot of complaints that WP8 have no sync with outlook through bluetooth or usb. Many people, like myself, don't like to go through the Cloud/skyware. I have had several Nokia Communicators with Bluetooth sync which was outstanding in many ways. For two years I have had HTC and solve the syncronisation with a program called Missing Sync. But they don't support WP8. You will have a better marketposition in the future when Nokia and Microsoft solved this for us users big and frustrating problem. I like my new Lumia 920 very much and is proud to show it for former Nokia communicatorusers. But immediately they raise the question - how about Nokias fine Bluetoothsync with the series of Comminicators.
As an daily working marketing and sales person for over 40 years I'm convinced that this will be Your best selling feature in the future. "Nokia Lumia user handle things in professionell and with secret - They use bluetooth-sync and avoid the cloud.

People like myself how a lot of files, things in our calenders, notes, contacts etc which we must keep confidential and not send to a "Cloud".
